  1. 1. Investigations of human cortical processing of gentle touch. A study with time-resolved electro-magnetic signal analysis

    Detta är en avhandling från Göteborgs universitet

    Författare :Elin Eriksson Hagberg; Göteborgs universitet.; Gothenburg University.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aβ afferent; C-tactile; touch; EEG; MEG; SEEG;

    Sammanfattning : The present work summarizes investigations of the temporal correlates of brain activity elicited by gentle, moving touch on the hairy skin in healthy participants and in epilepsy patients. Light touch to the hairy skin activates two distinct afferent classes: fast conducting, Aβ afferents and slowly conducting C-tactile (CT) afferents. LÄS MER

  2. 2. Affective touch throughout life: from cortical processing in infancy to touch perception in adulthood

    Detta är en avhandling från Göteborgs universitet

    Författare :Emma H. Jönsson; Göteborgs universitet.; Gothenburg University.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Affective touch; Touch perception; Cortical activation; C-tactile afferents;

    Sammanfattning : Affective, interpersonal touch is important for forming and maintaining social bonds. In the hairy skin of humans there is a specific type of nerve fibers called C-tactile (CT) afferents which are optimally activated by a light stroking of the skin, like a caress. LÄS MER

  3. 3. The Perception and Evaluation of Pleasant Touch and the Development of "Satiety" for Hedonic Tactile Experiences

    Detta är en avhandling från Göteborg : Reprocentralen Lorensberg

    Författare :Chantal Triscoli; Göteborgs universitet.; Gothenburg University.; Göteborgs universitet.; Gothenburg University.; [2016]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pleasant touch; CT afferents; Top-down mechanisms; Satiety; Liking; Wanting;

    Sammanfattning : Pleasant touch is a hedonic experience and one of the most powerful means for social bonding and for communicating affection. Touch similar to a human caress is detected by the “C tactile (CT) afferents”, a class of mechanoreceptors which respond preferentially to stroking velocities between 1 and 10 cm/s. LÄS MER

  4. 4. Hedonic, neural, and autonomic responses to prolonged gentle touch

    Detta är en avhandling från Göteborg : Psykologiska institutionen, Göteborgs universitet

    Författare :Chantal Triscoli; Göteborgs universitet.; Gothenburg University.; [2018]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; long-lasting touch; CT afferents; pleasantness; liking; wanting; satiety; orbitofrontal cortex; reward; heart rate variability;

    Sammanfattning : Physical contact among individuals, such as caressing and cuddling, is connoted by a strong emotional value, and is usually perceived as a pleasant and rewarding experience. C tactile (CT) afferents are a class of fibres that are specific channels for detecting touch at a caress-like veloc-ity (between 1 and 10 cm/s). LÄS MER

  5. 5. Machine learning for identification of brain activity patterns with applications in gentle touch processing

    Detta är en avhandling från Göteborg : Psykologiska institutionen, Göteborgs universitet

    Författare :Malin Björnsdotter Åberg; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Somatosensory; Machine learning; Pattern recognition; fMRI; Support vector machines; Neuroscience; Brain; BOLD; Signal processing; Artificial intelligence; Touch; Human; Unmyelinated; Sensory; Affective;

    Sammanfattning : Since the first mention of artificial intelligence in the 1950s, the field of machine learning has provided increasingly appealing tools for recognition of otherwise unintelligible pattern representations in complex data structures. Human brain activity, acquired using functional magnetic resonance imaging (fMRI), is a prime example of such complex data where the utility of pattern recognition has been demonstrated in a wide range of studies recently (Haynes et al.
